    Asexual Reproduction Asexual Reproduction Presentation Transcript

    • Asexual Reproduction Mr.Miller
    • Is this Statement true or false?
      • Two parents are needed to produced a new organism
    • What in the world is this?
    • This is a starfish Some starfish have the ability to regenerate if their limbs are removed
    • What is reproduction?
      • Reproduction is the process of producing offspring
      • Offspring - a new organism produced by one or two parents
      • There are two types of reproduction
        • Asexual Reproduction
        • Sexual Reproduction
    • What is asexual reproduction ?
      • Asexual Reproduction is the process of producing offspring with only one parent.
    • How does this happen?
      • There are several forms of asexual reproduction, which include:
      • Regeneration (Fragmentation)
      • Budding
      • Binary Fission
      • Mitosis
    • What is Budding?
      • Budding is a form of asexual reproduction
      • Budding involves the development pinching off of a new cell
      • Budding is very common in plants and fungi , but may be found in animal organisms as well, such as the Hydra . Usually, the protrusion stays attached to the primary organism for a while, before becoming free. The new organism is genetically identical to the primary one (a clone ).
    • Budding in a hydra
    • Regeneration (Fragmentation)
      • Regeneration is another form of asexual reproduction
      • During regeneration, an organism breaks into two or more parts.
      • Each part can grow into separate organisms
      • Starfish and sponges have the ability to reproduce asexually by regeneration
    • Binary Fission
      • Binary fission is a process of asexual reproduction in prokaryotic cells
      • Binary fission has four steps
        • 1. cell growth
        • 2. DNA replication
        • 3. Cell separation & growth
        • 4. The cell splits in two
    • Asexual Reproduction Poster
      • Instructions: You must create a poster that contains the following elements
      • Title (5pts)
      • Definition of Title term (10pts)
      • A drawing to represent each type of asexual reproduction(20 pts each)
      • Title to label the type of asexual reproduction be displayed (5 pts each)
      • A description of what occurs during this type of asexual reproduction (10 pts each)
    • What is mitosis?
      • Mitosis is the process of cell division in eukaryotic cells
      • Cells have a life cycle which is called the cell cycle. The cell cycle includes two stages:
        • Interphase
        • Mitosis
    • Which organisms reproduce this way?
      • Amoebas are single cell organisms that use mitosis to reproduce
      • The cells in the human body also reproduce through mitosis
    • Interphase
      • Before cells can divide their DNA must be replicated during interphase .
      • DNA is organized into structures called chromosomes
      • Then Cell Division occurs in a series of stages or phases
      • There are four phases in mitosis:
        • Prophase
        • Metaphase
        • Anaphase
        • Telophase
    • Prophase
    • Metaphase
    • Anaphase
    • Telophase
    • Cytokinesis
    • Lets Review What We Learned!
      • What is reproduction?
    • Reproduction is the process of producing offspring
    • What Are Offspring?
    • Offspring are new organisms created by one or two parents
    • What are the two types of reproduction?
    • Asexual Reproduction & Sexual Reproduction
    • What is Asexual Reproduction?
    • Asexual Reproduction is the process of producing offspring with only one parent
